Raster data GeoTIFF file (*.tif)
  Arc/Info ASCII file (*.asc)
  NetCDF file (*.nc)
Time series raster data GeoTIFF file (*.tif)
  Arc/Info ASCII file (*.asc)
  NetCDF file (*.nc)
  X band MP rader data (*.*)
Polygons ESRI Shapefile (*.shp)
  CSV file (*.csv)
Lines ESRI Shapefile (*.shp)
  CSV file (*.csv)
Points ESRI Shapefile (*.shp)
  CSV file (*.csv)

When you select [Geographic Data], a list of importable geographic data is shown as submenus. Select the geographic data you want to import and the [Select file to import] dialog (Figure 54) will open. Select the file to import the geographic data.

You can see the imported geographic data in [Object Browser]. Figure 55 shows an example of the iRIC window after importing a river survey data.

Additional operations dependent on file formats are explained below.

Topography file (*.tpo)

When the file to import is selected, [Filtering Setting] dialog (Figure 56) is shown.

Please edit Filter value when needed, and click on [OK] button to proceed.

Text file (*.csv, *.txt, *.xyz)

When you select a file, [Import Setting] dialog (Figure 57) is shown.

Please specify appropriate setting, checking [Preview] region, and click on [OK] button to proceed.

Cross-section data (*.riv)

When you import cross-section data, the selected file is checked for errors. If problems are found, [Problems Found in Data] dialog (Figure 58) is shown.

After that, [Cross-Section Data Import Setting] dialog (Figure 59) will open. Specify the import setting and click on [OK].

Japan MLIT Cross-section data (*.csv)

At first, please select the CSV file that contains distance marker data. Then [Select folder where cross section data exists] dialog is shown, so select the folder and click on [Select Folder] button.

When importing from Japan MLIT Cross-section data, the file is checked for errors. If problems are found, [Prolems Found in Data] dialog () is shown.

After that, just like Cross-section data (*.riv), [Cross-Section Data Import Setting] dialog (Figure 59) will open. Specify the import setting and click on [OK].

GeoTIFF file (*.tif), Arc/Info ASCII file (*.asc) (Raster data)

When you import GeoTIFF file (*.tif), Arc/Info ASCII file (*.asc) to import raster data, if information about coordinate system is not included in the file, [Warning] dialog (Figure 61) is shown, and [Select Coordinate System] dialog (Figure 62) is shown. Please select the coordinate system for the data to proceed.

GeoTIFF file (*.tif), Arc/Info ASCII file (*.asc) (Time series raster data)

When you import GeoTIFF file (*.tif), Arc/Info ASCII file (*.asc) to import time series raster data, time of date included in each file is recognized from file names.

When the file name matches one of the following patterns, the files will be imported automatically.

  • YYYY-MM-DD_hh:mm:ss
  • YYYY_MM_DD_hh:mm:ss
  • YYYYMMDD-hhmmss
  • YYYYMMDD_hhmmss
  • YYYYMMDD-hhmm
  • YYYYMMDD_hhmm

If the file name matches none of them, [File name pattern setting] dialog (Figure 63) is shown. Please input the pattern to correctly recognize time values from file names.

NetCDF file (*.nc)

When you import NetCDF file into geographic data that has dimensions other than position, the [Dimension Mapping Setting] dialog (Figure 64) will open. Setup the mapping setting about the dimensions, and click on [OK].

X band MP rader data (*.*)

When you import XRAIN rainfall data as geographic data, save XRAIN rainfall data files into one foler, and select one of them in the dialog. The, all rainfall data in that folder are loaded and imported.

ESRI Shapefile (*.shp)

When importing polygons or polylines from ESRI shape files, [Polygon (or Polyline) Import Setting] dialog (Figure 65) is shown. Specify the setting for importing name and value, and click on [OK] to proceed.
